EDM challenge 32 continued. Small sketch,150mm x 90mm done while I sat and waited 10 minutes for the museum to open. When I got home I used coloured pencils to finish it, and for the concrete wall I used a small sponge and stamp pads. I had not noted the colours used and had to resort to my memory, it’s amazing how hard it was to remember exactly what colours were where. I could have sworn there was blue but didn’t know where, hmmm maybe on the front. I have drawn it wonky, it is not your eyes! It is metal.
